The Astrobotic CubeRover traverses the terrain in the Granular Mechanics and Regolith Operations Lab regolith bin at NASA’s Kennedy Space Center in Florida on Dec. 10, 2020. The regolith bin simulates the mechanical properties of the Moon’s surface. NASA and Astrobotic employees put the CubeRover through a series of more than 150 mobility tests over several days to evaluate and improve wheel design. Also in the bin is NASA’s Regolith Advanced Surface Systems Operations Robot (RASSOR), a robotic platform designed to dig on the Moon. The regolith bin simulates the Moon’s surface.
